The roof insulation in your home is a critical piece of your roof’s system. It works hard to keep your house cool in the summer and warm in the winter. Let’s learn a little more about why roof insulation is so important.
R-Value
But first, let’s talk about R-value. R-value is a measurement system that grades types of insulation based on how well they keep heat from entering or leaving your home. A higher R-value rating shows a better-performing insulation type.
In Gig Harbor, Tacoma, and Port Orchard we are in R-value climate zone 4, which means any attic insulation should achieve an R-value between R-38 and R-60, depending on the current insulation levels. As you choose the right insulation, you will also want to consider the age and condition of your home.
It Saves you Money
According to the US Department of Energy, a properly insulated roof can help you save between 10 and 20% when it comes to energy consumption.
Controlling the internal building temperature insulation saves the need for energy because insulation reduces the amount of energy needed to heat and cool your home. Using less energy means you are keeping money in the bank and protecting the environment by leaving behind a smaller carbon footprint.
You Have Options
There are plenty of good options when it comes to insulating your roof. Here are some of the most common:
Fiberglass (batts or rolls)
Fiberglass insulation is by far the most widely used insulation in today’s homes. It’s inexpensive and effective, and it’s easy to install on your own. It comes in loose batts or rolls, and these come faced (lined with paper) or unfaced (no paper).
It is an ideal option for attic insulation, especially if you have an attic with standard-spaced joists and beams and minimal obstructions. It can be cut to size/fit but will still leave some gaps here and there. To maintain its R-value around vents, it needs to be cut accurately.
Loose-Fill or Blown Insulation
Loose-fill or blown-in insulation is a type of insulation material that is made up of tiny fibers from recyclable materials like paper, plastic, and molten glass and chemicals to make it heat-resistant. It can adapt to the shape of any space without obstructing the structures of your home.
Spray Foam Insulation
Spray foam insulation is an excellent option when it comes to insulating your attic space.
It has one of the highest R-values making it a great option. It’s sprayed and seals any gaps, hard-to-reach places, and crevices that are often impossible to get to with any insulation.
We do want to mention that if you chose spray foam insulation, know that it needs to be done by a professional. Professionals have the right equipment and skill needed.
Installation can be a DIY
Except for spray foam (mentioned above), fiberglass and loose-fill insulation can be installed by most homeowners. After you determine the type of insulation you want to use, you’ll want to follow these steps.
